Absolute newby here. I have flown FSX for many years and finally decided to upgrade to P3Dv4.5. I purchased the Toposim bundle, but now I don’t know how or where to install it. Do I treat it like any other scenery (and use Addon Organizer), or does it go in a special place? Since this is completely new to me, I need a LOT of help.
I have searched through here, but it seems everyone knows much more than I do, and the threads I read are above my head.
